*/alias [filename] <aliasname> <command>*

Add/remove/replace any single line alias.

<pre>
/alias /hello /me says hello
</pre>

This will replace the first matching alias with the new command.

To remove an existing alias:

<pre>
/alias /hello
</pre>

If you want to add/remove/replace a alias in an existing file, use:

<pre>
/alias hello.txt /alias /me says hello
</pre>

If no filename is specified it will use the first match or the first loaded alias file.
